I recently attended a foundation brake training class at engine city technical institute in Union, NJ. This was a hands-on class that covered all the components that are essential for air brakes to work properly. I learned a few interesting facts such as, how the s-cam produces torque and minimum and maximum radial and axial play. We learned on both Eaton and Rockwell/Meritor axles, two of the most used in today’s truck market.
I learned about proper pushrod length for the air chamber and OEM adjustment procedures for maximum stopping. Another important topic that was covered was proper axle wheel bearing installation specifications. I was shown the correct procedure to adjust wheel bearings using the manufacturers guidelines.
Overall, this class was extremely knowledgeable, especially from all of the hands-on-training time involved. I came away from this class with a better understanding of braking systems and their operation.
